ToaZZ whom, itv may concern: I strains, and defects which have heretofore Be it known that I, JOHN F. OCONNOR, a een incident to the making of side plates or lcitizen of the United States,'residing in Chistop-castings of the old constructions, wherecago, in the county ofCook and State of Illiin the stops or shoulders forni right angle or 55 nois, have invented a new and useful Im- T sections with the main plate or web of the provement in Draft-Rigging for Railwaycasting.

The side plate or stop-casting F, there beone secured to each draft-timber by suitabe bolts is furnished with a plurality of stops or shoulders for the followers to abut against, each side plate or sto casting having preferabl four stops or s oulders f fl,

i f3, and fl an also four intermediate stops or shoulders f5 f and jl f8, the intermediate stops serving to limit the compression of the springs. The main-web F of the side late or stop-casting is of substantially unJ crm` thickness throughout, and theseveral stopshoulders are formed by integral bends or convolutions F2 inthe web F', the `integral bends or convolutions F2 being upright and part of the casting, and the horizontal or lonhorizontal or longitudinal strengthening ribs reducing any increased 'increased thickness of the casting at the gitudinal stren thening ribs or flanges jD f1,

. f 11, and 12 are ikewise produced by horizontal-ben s or convolutions F3 in the main web Ff of the 'side plate or sto -casting without ody of metal or o'int where these horizontal ribs or flanges join with the main web. The bend or convolution F", which for-ms the' intermediate longitudinal ribs or flanges f1 f is prefer ably centrally located. At the points where the upright bends or convolutions in the main web F would intersect with thehori'- zontal bends or convolutions the horizontal bends' or convolutions are omitted, as willn be readily understood from Figs. 2, 3, 4, 5, and 7, so that no increased body of metal or increased thickness of the casting is, in fact, produced at such intersections.

My improved side plate or stop-casting is thus composed of a web of substantial uni form thickness throughout, while at the saine time having the necessary upright stope shoulders and also the necessary or desired or flanges.

I claim- 1. 'In a draft-rigging for railway-cars, the combination with the draw-bar, springs and followers, of side plates or stop-castin s each consisting of a cast web of substantie lyuni- Vform thickness throughout, free from T and other Bangle-like sections, and having integral uprig t convolutions therein forming upright stop-shoulders, and having also horizontal convolutions therein forming longitudinal strengthening ribs or flanges, substanti ally as specified.

3. A railway raft-rigging side plate or stop-casting, consistin of a cast web of substantially uniform thic ess throughout, free from T and othervflangedike sections, and furnished with a series of upright convolutions therein forming stops or shoulders for the followers to abut a ainst, and furnished' with horizontal or longitudinal convolutions therein forming longitudinal strengthening ribs or ilan es, substantially as specified.
